Hart manufacturing makes three products. each product requires manufacturing operations in three departments: a, b, and c. the labor-hour requirements, by department, are as follows: department product 1 product 2 product 3 a 1.95 3.45 2.45 b 2.90 1.90 3.40 c 0.70 0.70 0.70

during the next production period, the labor-hours available are 540 in department a, 440 in department b, and 140 in department c. the profit contributions per unit are $34 for product 1, $37 for product 2, and $39 for product 3.

formulate a linear programming model for maximizing total profit contribution. for those boxes in which you must enter subtractive or negative numbers use a minus sign. (example: -300)

let pi = units of product i produced

The business cycle is the periodic but irregular up-and-down movement in economic activity, measured by fluctuations in real gross domestic product (gdp) and other macroeconomic variables. a business cycle is typically characterized by four phases—recession, recovery, growth, and decline—that repeat themselves over time. economists note, however, that complete business cycles vary in length. the duration of business cycles can be anywhere from about two to twelve years, with most cycles averaging six years in length. some business analysts use the business cycle model and terminology to study and explain fluctuations in business inventory and other individual elements of corporate operations. but the term "business cycle" is still primarily associated with larger (industry-wide, regional, national, or even international) business trends.
